Designed for specific application PS11035, by Mitsubishi Electric, is flat base insulated type Power Supply Module, consisting of 3-phase Bridge for AC to DC conversion. IGBT Inverter Bridge for 3 Phase is configured using latest diode and gate technology. PS11035 has motor rating of 1.5KW at 200V AC with Inverter output 100% capacity of 7.0A rms (root mean square) and for 60Sec it can provide up to 10.5A rms that is 150% of its Output.
Following are the main characteristics of the module;
1- CONTROL FUCTIONS
a. P-Side IGBTs: Drive circuit, high-level-shift circuit, bootstrap circuit supply scheme for Single
Control-Power-Source drive, and under voltage (UV) protection.
b. N-Side IGBTs: Drive circuit, DC-Link current sense and amplifier circuits for over current
protection, control-supply under-voltage protection (UV), and fault output (FO)
signaling circuit.
c. Fault Output: N-side IGBT short circuit (SC), over-current (OC), and control supply under-
voltage (UV).
d. Inverter Analog Current Sense: N-Side IGBT DC-Link Current Sense.
e. Input Interface: 5V CMOS/TTL compatible, Schmitt Trigger input, and Arm-Shoot-Through
interlock protective function.
2- MAXIMUM RATINGS
a. For Inverter: Supply Voltage 450 V with surge range of 500V, Collector Current for each output
at case temperature of 25°C is +/-20A with mean peak Value of +/-40A.
b. For Converter: Recommended input Voltage is 220V and repetitive peak reverse voltage is
800V. DC output rated current of 3 phase rectifying circuit is 20A.
c. For Control unit: Supply Voltage range is -0.5V to 20V and Fault output current is 15mA.
Application specific inverter and converter package is designed as noiseless motor control module. System has thermal capacity of 125°C max for Junction Temperature and minimum value of -20°C. Module is equipped with Current Abnormality Protection which is achieved by filtering the N-Side DC Bus current. Over Current Protection is deployed with 10 micro seconds when the line current reached the 250% of rated Load Current.
