# Voltage Amplitude Control Circuit (50)

**Voltage amplitude control circuit** (50) of Figure (3-5) performs several functions simultaneously:

First, regulates car **battery electrical voltage potential** (32) of Figure (3-15) being applied to **primary coil** (26) of Figure (3-21); and secondly, regulates **gas pressure** of **Fuel Cell** (120) of Figure (3-22), as graphically depicted in Figure (3-15).

<p class="callout info">**Regulator stage** (27) of **circuit** (50) converts **battery voltage potential** (29) of Figure (3-6) via **electrical terminal** (31) of Figure (3-5) as to Figure (3-6) into a **analog voltage signal** (32) of Figure (3-15) which corresponds to but is **electrically isolated** (*crossover voltage from two separate power supplies*) from incoming **gas volume signal** (23) of Figure (3-14), as shown in Figure (35).</p>

**Variable voltage range** (32a xxx 32n) from **one** (1) up to **twelve** (12) volts (regulating battery voltage) is applied across **primary coil** (26) of **Voltage Intensifier Circuit** (60) of Figure (3-21).

Second **regulator stage** (28) simply acts and function as a **gas regulator** (33) by preventing **Fuel Gas** production beyond a predetermined **gas pressure level** (34) of Figure (3-15) during **Fuel Cell** operations and, as such, <span style="text-decoration: underline;">maintains constant gas pressure</span> to **Fuel Injectors** (36) of Figure (3-1) regardless of engine performance (R.P.M. response).

<p class="callout warning">If for example, **Fuel Gas** production is <span style="text-decoration: underline;">greater than demand</span>, then, **analog signal** (32) is reduced to proper **voltage level** (35) <span style="text-decoration: underline;">(voltage level directly determines gas pressure via **Resonant Action**)</span> required to maintain **gas pressure** (34).</p>

Conversely, **analog signal** (32) is always allowed to exceed **voltage level** (35) during **injection** (36) of Figure (3-1) until **gas-point** (34) is reached.

<p class="callout info">In cases where **linear voltage** (32) drops (descending value) below **gas-point** (35) then **gas regulator stage** (28) increases **voltage amplitude** (32a xxx 32n) (analog voltage) to **voltage point** (35).</p>

If **gas pressure** (34a xx) should exceed **gas point** (35) during injector off-time, **gas pressure release valve** (75) of Figure (3-24) (**gas venting** 37 of Figure 3-15) expels **Fuel gases** (88) until **gas point** (34) is either reached or a delay timing circuit activates **Safety Control Circuit** (14) of Figure (3-6) which, in turns, switches off or disconnects **applied electrical power** (28) to **Fuel Cell electrical system** (400) of Figure (3-6).
